import axios from 'axios'

export function request(config) {
  //1.创建axios的实例
  const instance = axios.create({
    baseURL: 'http://172.31.227.85:51810/api/upload/chain',
    timeout: 5000
  })

//2.axios的拦截器
//2.1请求拦截的作用
  instance.interceptors.request.use(config => {
    return config
  }, err => {

  })
//2.2响应拦截
  instance.interceptors.response.use(res => {
    return res.data
  }, err => {
    console.log(err);

  })
//3.发送真正的网络请求
  return instance(config)
}
